Abstract:
Characterization of reservoir deliverability is fundamental in economic development of any field. In the Bakken this understanding is particularly important because of the reliance on massive hydraulic fracture stimulation. Determining well deliverability potential, by conventional drill stem tests (DST) or traditional Wireline Formation Tester (WFT) methods has led to mixed success in Bakken. On the other hand, the mini-DST has definitely increased the reliability and success rate of pressure transient tests.
The interpretation of mini-DST drawdown and buildup pressure responses from each tested interval can provide an assessment of the relative flow potential of each formation. The analyses and observations have provided very useful insight into a better understanding of the near-wellbore flow mechanism in Bakken. In this talk, the operation of mini-DST equipment, test interpretation procedure and field examples to demonstrate the effectiveness of such mini-tests will be shown. The entire experience can also serve as a basis for test design in similar low-permeability reservoirs around the world.
